My website is no longer visible

We had an IT person, but she ghosted us, for several months. I finally got control of the e-dress associated with the site, and I got mail saying someone was trying to transfer a site to us. That would be great, but the invitation expired before I could see it. It could be spam, or it could be her. She won’t answer our texts.

I get an error page when I go to the url. Does Wix make anyone available to at least advise on this, or are we just effed?
